How to open a port on the Sitecom WL-109

Sitecom WL-109 routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

  1. Setup a static ip address on either your computer or device that you want to forward a port to.
  2. Login to your Sitecom WL-109 router.
  3. Navigate to the port forwarding section.
  4. Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Sitecom WL-109 router.

We think that forwarding a port should be easy. That's why we created Network Utilities. Our software does everything that you need to forward a port.

Step 1

It is important to setup a static ip address in the device that you are forwarding a port to. This ensures that your ports will remain open even after your device reboots.

  • Recommended - Our free program will setup a static IP address for you.

  • Or follow our Static IP Address guide to setup a static IP address.

Step 2

Now we are going to login to your Sitecom WL-109 router. Your router has a web interface, so you will login to it using your web browser. This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

Open up your web browser and find the address bar. It should look something like this:

In the picture above the address bar has in it. Just replace all of that with the IP address of your Sitecom WL-109 router. Your router's ip address can also be refered to as your computer's default gateway.

By default the IP address is set to:

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:

You should see a box prompting you for your username and password.

  • The Default Sitecom WL-109 Router Username is: admin
  • The Default Sitecom WL-109 Router Password is: password

Enter your username and password, and then click the Login button to log in to your Sitecom WL-109 router.

Sitecom Usernames and Passwords

If your username and password do not work then please visit our Default Sitecom Router Passwords page.

If you still can't login to your router because you forgot your Sitecom WL-109 router username and password, use our How to Reset a Router Password guide to set your Sitecom WL-109 router back to its factory settings.

Step 3

Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:

Step 4

Now we are ready to enter some data in your router. In order to show you exactly how to configure your router we need you to answer 2 questions:

Application :
IP Address :

(The IP Address to forward to should be the same "static ip address" that you setup above)

Our router simulator shows you exactly what data to enter in your router based on your choices above. We are currently showing the ports for XBox Live. You should fill out the boxes in the router as you see them here:

When you're finished, click Save near the bottom of the screen to save your changes.

Test if Your Ports are Open

Now that you have forwarded ports on the Sitecom WL-109 you should test to see if your ports are forwarded correctly.

To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Our Open Port Check tool is the only online port checking tool with Guaranteed Results.

Service Definition  
Port Start
Port End

Go ahead and name your service. It doesn't really matter what the name is, but something easy to remember would be good. Select tcp or udp under type. If you are unsure of the type just select both. Last put in the Start and Finishing port numbers. If the service only requires one port, put that port number in both the start and the finish box. You may need to setup multiple services, depending upon the number of ports/port ranges the software you want to run requires. Click Save when you have finished. Now we need to go to the second section to continue setting up our port forwarding. Under Security in the left hand menu click Rules.
Once again you should see the following menu.

Go ahead and click Add in the Outbound or Inbound services section. If you are unsure whether the program you are using will use these ports for inbound or outbound traffic, repeat steps 7 through 9 for both Inbound and Outbound.

Send to LAN Server
Wan users

Select the service we previously created. Action should be set to ALLOW always. Enter the ip address you want to forward these ports to in Send to LAN Server. If you are forwarding ports so you can run a program on your computer, you should enter the your computers ip address into this box. Wan Users should be set to Any, unless you want to limit who you want to connect to these ports. This would be useful, lets say, if you only wanted your office computer to be able to ftp into your home computer. In that case you would put your office computers ip address in both the start and finish box. Generally log should be set to never, unless of course you want to create a log of network activity.
When you are finished with that configuration go ahead and click Save.
